The PTH03060 is a next generation series of non-isolated dc-dc converters offering some
of the most advanced POL features available in the industry. The primary new feature
provides for sequencing between multiple modules, a function, which is becoming a
necessity for powering advanced silicon including DSP’s, FPGA’s and ASIC’s requiring
controlled power-up and power down. Other industry leading features include margin
up/down controls, pre-bias start-up capability and efficiencies up to 93% . The PTH03060
has an input voltage of 2.95 Vdc to 3.65 Vdc and offers a wide 0.8 Vdc to 2.5 Vdc output
voltage range with up to 10 A output current, which allows for maximum design flexibility
and a pathway for future upgrades.
